When dealing with pipe the volume is more important, therefore, I would use the inside diameter.
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
The area is the inside. The perimiter is around. If its a rectangle, to find the area you multiply the lengths of two sides
It is: 0.5*pi*7 = 11 square feet rounded
Take the inside diameter, from inner edge to opposite inner edge and going through the middle. Divide this by two to give you an inside radius. Multiply this by itself to give the radius squared, then multiply this by Pi to give inside area. Finally, multiply this by the length of the pipe to give the volume.
Inside area: pi1.51 square inches
The ID is the inside diameter, you can use a tape measure and measure the open end of the pipe from inside edge to opposite inside edge

inside the exhaust pipe. remove pipe to find washer(aka governor) in head pipe.
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
I'm guessing you're referring to Mario & Luigi: Bowser's Inside Story. The 'Flame Pipe' area is on the center-right area of the map, north-east from Toad Square.
Measure the inside diameter and multiply it by 3.14159 (pi)

Volume = Cross-sectional area X Length. So Area of a circle = PI times radius². Approximate PI with 3.14, then radius = diameter / 2 = 3 inches. (pipe normally is specified in inside diameter). So Area = (3 in)² x 3.14 = 28.26 in². Now multiply that by length of pipe (in inches) to find volume capacity (in cubic inches) of that section of pipe.
Hello, Velocity in a pipe is the flow divided by the area. If the pipe is full, the area is simply pi*r². Here is a useful calulator for full pipes: http://www.tasonline.co.za/toolbox/pipe/velocity.htm
take the outside diameter and subtract the thickness twice.
